The Interrupted Goode Homolosine Projection is not one that NCAR
Graphics handles, though NG does include the sinusoidal projection
and a form (but maybe not the right form) of the Mollweide projection,
both of which are used by the IGHP.
You've probably already Googled this and so know about this site:
http://edcdaac.usgs.gov/1KM/goodesarticle.asp
It describes the projection and an algorithm for mapping from lat/lon
to the projection plane and vice-versa. I think I would find it rather
heavy going to translate this into a piece of code, but maybe you can
contact the author and obtain his code and/or get suggestions as to
how to proceed.
